The intervention group received additional task-oriented repetitive training using the SaeboFlex orthosis, a dynamic wrist-hand-finger orthosis designed to facilitate upper limb rehabilitation in stroke participants. The SaeboFlex orthosis is a custom-fabricated, non-electric mechanical device that assists participants with significant upper extremity weakness, particularly those without active finger extension, in performing repetitive task practice

Both the control and intervention groups received regular rehabilitation, which included physical therapy, occupational therapy and visual cognitive rehabilitation.

During the regular rehabilitation program, participants received a comprehensive range of therapies aimed at improving their overall functional abilities and quality of life. The key components of the regular rehabilitation included:

The SaeboFlex orthosis was fitted individually for each participant in the intervention group. The orthosis was adjusted to ensure proper alignment and comfort.

Participants were instructed on how to don and doff the orthosis correctly and safely.

The orthosis positions the wrist and fingers in extension in preparation for grasp and release activities, enabling participants to perform functional tasks despite limited voluntary movement.

Task-Oriented Repetitive Training:

The intervention consisted of 45-minute sessions, conducted twice a week, over a period of 12 weeks.

Each session focused on repetitive, task-oriented exercises designed to improve motor function and enhance neuroplasticity.

Training Activities:

• Moving the Ball
• Bringing the Ball to the Mouth
• Reaching Towards a Target
• Manipulating the Ball Around a Target
• Placing the Ball into Tubes
• Throwing the Ball
• Catching a Rolling Ball

The ARAT is a widely used, validated, and reliable measure of upper extremity function. It includes four subscales: grip, grasp, pinch, and gross motor movements. The highest total score is 57, indicating the best performance

Goniometry is used to assess joint range of motion of the trunk, and flexion and extension degrees are recorded.

The LOTCA test is used to evaluate individuals' cognitive abilities before and after intervention. It consists of 22 items grouped into two assessments: pre-treatment and post-treatment. The test assesses orientation, visual-spatial perception, visual-motor organization, thinking skills, and attention. Performance on each subtest and total scores are calculated. In our study, we evaluated only the visual-motor organization and visual-spatial perception parameters

This 21-item scale is used to assess the level of depression. Each question is scored from 0 to 3, resulting in a total score ranging from 0 to 63. Scores between 0-13 indicate no depression, 14-24 indicate moderate depression, and scores above 25 indicate severe depression. The scale has been validated and adapted for the Turkish population

The Barthel Index, developed by Barthel and Mahoney in 1965, is a reliable and valid instrument used to assess individuals' independence in activities of daily living. In this study, the index was used to determine the level of independence in daily activities. The index scores range from 0 to 100, with scores of 0-20 indicating complete dependence, 21-61 indicating severe dependence, 62-90 indicating moderate dependence, 91-99 indicating mild dependence, and 100 indicating independence

This test evaluates motor development in stroke patients and defines it into 6 stages. The absence of voluntary movement is categorized as stage 1 (flaccid stage), while the presence of isolated movements is considered stage 6. Evaluation is performed separately for the upper extremity, lower extremity, and hand
